Uterine fibroids can grow as a single tumor, or there can be many. Fibroids can be as small as an apple seed or as big as a grapefruit. While not all women with fibroids have symptoms, for some, the symptoms can be severe. The problems that fibroids can cause include:
  • Heavy, prolonged or irregular menstrual periods
  • Severe menstrual cramps
  • Bloating
  • Abdominal swelling
  • Pain or pressure in the hips, pelvis or legs
  • Frequent urination
  • Constipation
  • Anemia
  • Pregnancy and fertility complications

The most common symptom of fibroids are bleeding and cramping, says Edmond Pack, MD, an OB/GYN at Southern Hills Hospital. In this video, he says that routine examination can discover fibroids as well.
Most commonly, uterine fibroids are small and do not cause symptoms. The main symptoms that do occur, however, can be classified into three categories: abnormal uterine bleeding, pelvic pressure and pain, and problems with reproduction. Abnormal bleeding is the most common symptom of fibroids and typically includes heavy or longer periods. Pain or pressure symptoms are caused by a bulky or irregularly shaped uterus from the fibroids in the uterine wall. These can occasionally put pressure on the bladder or the rectum, causing problems with urinating or stooling. Some women also report pain with menstrual periods (dysmenorrhea) or pain with intercourse (dyspareunia). Fibroids have also caused problems with reproduction that make the uterus unfavorable for pregnancy. For example, they can sometimes cause women to have problems with getting pregnant, miscarriage or premature delivery of the baby.

  • Feeling of fullness in the pelvic area (lower stomach area)
  • Enlargement of the lower abdomen
  • Frequent urination
  • Pain during sex
  • Lower back pain
  • Complications during pregnancy and labor, including a six-time greater risk of cesarean section

  • abnormal bleeding between menstrual periods
  • pelvic pain (caused as the tumor presses on pelvic organs)
  • frequent urination
  • low back pain pain during intercourse
  • an enlarged abdomen, which causes a constant feeling of fullness or pressure

The most common symptoms seen with fibroids are heavy bleeding as well as painful menses. Some patients also complain of a fullness in the pelvic area or bloating in their abdomen. If the fibroids are in a certain position in the uterus, they can effect the bladder or the bowel causing urinary and fecal frequency and urgency. Some patients also have a significant amount of pelvic pressure, pelvic pain, and low back pain from their fibroids.

Symptoms of uterine fibroids, or myomas, may vary depending on where the fibroid develops and how large it is. In many cases, uterine fibroids don't cause noticeable symptoms. If uterine fibroids do cause symptoms, they most commonly cause heavier menstrual bleeding, or they may prolong menstrual bleeding to last longer than seven days. Sometimes, uterine fibroids may cause a feeling of pressure of fullness in the pelvic area. Other symptoms may include pelvic pain, frequent urination, pain during intercourse, enlargement of the lower abdomen, constipation, or back pain. In rare cases, degenerating fibroids (fibroids that start to die if they don't have enough blood supply) may cause severe pain.
